: These are global electromagnetic resonances excited by lightning strikes in the cavity between the Earth's surface and the ionosphere. They create magnetic fields that are coherent over thousands of kilometers, potentially causing correlated noise between distant detector sites.

: External factors like nearby electronic infrastructure or even passing trains can create detectable magnetic disturbances. 2. How Magnetic Fields Disrupt Detectors Problems of intense magnetic field in gravitati...

: Interferometers use permanent magnets and coils to control the position of their mirrors (test masses). External magnetic fields exert direct forces on these magnets, moving the mirrors and creating a false signal. : These are global electromagnetic resonances excited by

Magnetic fields interfere with the interferometer through several "coupling" mechanisms: Problems of intense magnetic field in gravitati...

Magnetic interference in GW detectors stems from both natural and human-made sources:

: Magnetic fluctuations can induce noise in the sensitive cabling and control electronics used to read out the detector's data. 3. Impact on Scientific Discovery

: Fluctuating magnetic fields induce currents in the conductive structures of the detector (like the "payload" holding the mirrors), which in turn create secondary magnetic fields and forces.
